I have finished the Alex Cross series through book five, and I have six through nine on the TBR shelf now.
I have also read the first two Woman's Murder Club books. I thought I had the third, but it is NOT on my TBR shelf for some reason.
Of his non-series books I have read most. The Thomas Berryman Number, See How They Run (previously titles The Jericho Commandment), Black Friday (Also titled Black Market), Hide & Seek, The Midnight Club, When The Wind Blows, Cradle & All (Previously titled Vergin), The Jester and The Lake House.
I am only missing four books at this time. (That is until he releases another.)
